ulllll Patented May 16, 1933 UNITED STATES PATENT OFFEE SAMUEL SEGAL, 0F NEW YORK, N. Y., ASSIGNOR TO SEGAL- yEJIEELY RAZOR CORPORA- TION, OF NEW YORK, N. Y., vA CORPORATION OF NEW YORK RAZOR Application inea December s, 192s. serial No. 324,662.

This invention relates, in certain aspects, to a razor and, in others, to a sharpening device, as well as a combination of both, and the present invention aims to provide structurally and functionally improved units of this nature.

It is an object of the invention to provide a razor in which the parts may beadjusted readily to shaving 'positions and in which these parts, moreover, may be cleaned and dried with facility and in which, additionally7 it will not be necessary to disassemble the razor in the event that it is desired to sharpen the blade, it being, however, readily feasible for the user to replace an old blade with a new blade when this becomes necessary.

It is a further object to furnish a sharpening device which will be so constructed that the razor need not have its parts disassembled in order to associate these units with each other and in operative relation, the said sharpening device being readily operated.

An additional object is that of furnishing units of this character, the parts of which will be relatively few in number and individually simple and rugged in construction, these parts being capable of manufacture largely by automatic machinery and being, moreover, capable of being assembled by relatively unskilled labor to provide elements rendering useful service over long periods of time with freedom from mechanical difculties.

With these and further objects in mind reference is had to the attached sheet of drawing illustrating practical embodiments of the invention and in which v Figure 1 is a transverse section of one form of razor; s

Fig. 2 is a partly sectional side view there- Figs. 8, 4e and 5 are perspective views of the elements forming the complete assemblage;

Fig. 6'is a sectional side view of a razor of slightly different construction from that shown in the preceding views g l v Figs. 7 and 8 are plan and sectional side views respectively of still another form of razor and showing the same in association with a sharpening device;

Fig. 9 is a somewhat diagrammatic view of a modification of one of the elements of the sharpening device, and

Fig. 10 is a partly fragmentary plan view of a razor head and blade, the construction of which is slightly modified over the constructions shown in the preceding views.

Referring primarily to Figs. 1 to 5, it will be noted that the reference numeral 10 indicates a tube which provides the handle proper. Enclosing the upper end of this tube is a sleeve 11 which is rotatably secured to a collar 13, the sleeve being knurled as at 14 and having screw-thread engagement with the tube, as has been indicated at 12. Secured to the collar 13 is a guard 15 which may be formed with a longitudinally extending groove 16 and have its edges in the form of a comb 17. Aflixed to the upper end of the tube is a mounting member 18 with which a clamping plate 1,9 cooperates, this plate having downwardly extending prongs 21 to pass through openings 22 in the member 18 and being, moreover, formed with a screwthreaded opening 23 to be engaged by the upper and correspondingly threaded end of a rod 24 extending within the tube and having its lower end projecting beyond the same and terminating in a knob 25. With a view to preventing displacement of the rod from within the tube, although permitting lim'- ited longitudinal movement of these elements with respect to each other, the rod may be reduced and the tube may carry an inwardly extending lug or set screw 26. Thus, the clamping plate may be adjusted with respect to the mounting member 18 and the guard 15, and in view of the fact that the adjacent faces of these elements are preferably concavo-conveX, a blade 20 interposed between the same will, by this adjustment, be placed under a greater or lesser degree of tension and accordingly, the cutting edges of this blade will be moved farther away or closer towards the serrated -edges of the guard. Additionally it will be noted that substantially the same adjustment may be furnished by turning the sleeve 11 with respect to the tube but, moreover, by turning the sleeve to a sufficient extent all of the elements associated therewith may be moved downwardly along the tube to a point adjacent the lower end of the same, and screw threads 27 may be furnished at this point to engage with the threads 12 of the sleeve and thus retain the guard member wholly retracted.

N ow referring to the form of razor shown in Fig. 6, it will be noted that the handle is furnished by a pair of axially aligned, rotatably connected tube portions 28, 29. rlhe clamping plate 30 carries an inwardly er@ tending rod 31 terminating in a screwthreaded portion 32 engaging the correspondingly threaded bore of the tube 28. The guard 33 has openings through which the prongs 34 carried by the clamping plate eX- tend and a blade is interposed between these elements in the usual manner. Obviously, by simply turning the tube 28 with respect to the tube 29, the desired adjustment may be achieved readily. Additionally, if the tube is turned to a sufficient extent with respect to the rod 31, these parts will disen gage, permitting a consequent separation of the guard with respect to the clamping plate. incidentally, it will be noted that in operation the tube 29 may readily be grasped between the fingers of one hand while the tube 28 is turned with respect to the same by the fingers of the other hand, thus affording a maximum of convenience to the user.

Now with reference to the form of razor shown in Figs. 7 and 8, it will be noted that the clamping plate 35 has secured to it a rod 36 formed with threaded portions 3T and 38, this rod having key-ways 39 extending longitudinally of its body and mounting a tubular handle 40 having a portion of its bore correspondingly threaded and which handle has rotatably attached to it a guard 41. This guard, as has been best shown in Fig. 10, has inwardly extending hns 42 slidably mounted within the grooves or key-ways 39. As a consequence, the guard may be freely moved longitudinaly of the rod 36, but will not turn with respect to the same and, in view of the fact that this rod is aiixed to the clamping plate a relative rotation of these elements with respect to each other will be also precluded. The usual adjustment for tensioning the blade will follow by turning the tube with respect to the rod, and the tube may be maintained in retracted position if the threaded bore portion thereof is engaged with the threads 38 adjacent the outer end of the rod.

Now referring to the sharpening` device it will be noted that the same conveniently includes two pairs of rollers 43 mounted withn in a casing 44, these rollers being connected by a gearing 45 and driven conveniently by a crank 46. rlhe casing embraces a pair of cover portions 47 which are pivotally connected to the base of the casing and mav be swung upwardly with respect thereto to correspondingly move the rollers and permit a removal of the razor head or an introduction thereof into the space defined between the rollers. Extending from the base of the casing are studs 48 and the cover portions of the casing are provided centrally of their meeting edges with an opening 49 of a size adequate to permit of the passage of the rod 36 of the razor. At this time it will, moreover, be noted that the prongs of the clamping plates 35, 30 and 19 are each tubular and of a size such that the pins or lugs 48 may enter them. As a consequence, with the cover portions of the sharpening device raised and the guard portion of the razor retracted, the clamping plate thereof may readily be brought to the position shown in Fig. 8 by simply permitting the pins to enter the bores of the prongs and the clamping plate to bear against the enlarged portions of the pins. Now, upon the cover portions of the sharpening device being swung to closed position and the crank being turned, the stropping surface provided preferably by spirally disposed leather strips 50, will efficiently sharpen the cutting edges of therazor and thereupon, by simply raising the cover portions of the casing and applying the guard to the clamping plate, the razor will be ready for use. Incidentally, while considering the position of the clamping plate with reference to the sharpening device it will be observed that according to the present invention the outer face of this plate may be grooved, as at 51. As a consequence, the upper ends of the pins will, upon the razor being positioned, engage within this groove so that, by a very slight additional movement, the pins may be projected within the prongs 21. In the form of razor shown in Figs. 1 to 5 the retraction of the head follows by simply rotating the sleeve 1l. ln the form of razor shown in Fig. 6 a corresponding movement of the parts may be effected by simply rotating the tube with respect to the rod 31. This rod will serve as a handle in positioning and removing the clamping plate and blade from the sharpening machine. In the form of razor illustrated in Figs. 7 and 8 a rotation of the tube 40 serves to produce the desired result, it being observed that the guard will always maintain its properly aligned position by virtue of the key and groove construction employed.

It will be obvious, referring to Fig. 9, if it is not desired to utilize pins upstanding from the base of the sharpening device, that a rest 51a might be employed which would provide a saddle portion cooperating with the clamping plate to accurately position the cutting edges of the blade with reference to the stropping surfaces, and, finally, as in Fig. 10, the prongs 52, as well as the openings in the blade and the corresponding openings in the guard, might be made of oval or other contour to assure, if necessary, the use of a blade of a certain manufacture in connection with the razor.

F rom the foregoing it will be understood that, among others, the several objects aforementioned have been achieved. Obviously, numerous changes in construction and rearrangements of the parts might be resorted to without departing from the spirit of the invention as deined by the claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A razor including, in combination, a clamping plate, a handle, a second plate mounted upon said handle for association with said rst named plate, a guard, a sleeve mounting said guard, means associated with said handle and said sleeve whereby said guard may be raised or lowered with respect to said handle and a screw threaded rod slidable within said handle to retain said lirst named plate in Contact with said second named plate.
